Razon-BLADE Homann. i

Application filed February 18, 1927'. Serial No. 169,330.

My invention relates to a devicefor holding a safety razor blade so thatthe latter can be readily stropped, or utilized for varlous purposessuch, for instance, as a paint scraper, corn trimmer, seam ripper,eraser', and as a general utility knife.

One object of the invention'is to provide a simple and inexpensiveholder embodying two spring plates between which the razor blade can bequickly and firmly clamped for use, or quickly released.

In order that the invention may be fully understood, reference will nowbe had to the accompanying drawing, in which:

Fig. l is a side elevation of the. device holding a razor blade. QFig..` 2 is a longitudinal section on line 2 2' of Fig. i. y

Figs. 3 and 4 are detailside elevations of the two spring platesembodying the invention. 1

Fig. 5 is a vplan showing .the manner in which the spring plates arelbowedin oppositedirections to each other@y Fig. 6 isa detaillongitudinal sectional view of one ofthe spring plates. Y j I Incarrying out the invention Iemp'loy two complemental spring plates 2 and4, which areslightly bowed longitudinally as shown by Fig. 5. The springplate 2 includes a handle member 6 and a blade clamping element 8, whichlatter is narrower than' the former and tapers towards its outer end.The clamping element 8 is provided with a hole 10vand a' slot 12, andthe handle mem-v ber 6 is provided with an aperture 14 which is spaceda. short distance from the sloty12. The hole 10, the slot 12 and theaperture 14 are preferably arranged along the longitudinal axis of thespring plate 2, as shown more clearly by Fig. 8.

The spring plate 4 is similar in shape to the spring plate 2 and has ahandle member i6 and a blade clampingelement 18, which latter isnarrower than the former and tapers towards its outer end. clampingelement 18 is providedV with'two lateral projections 20 and 22 which arespaced apart to enter the hole 10 and the slot 12, respectively, of theclamping element 8. The handle member'l is provided with `a laterallyprojecting hook 24,-which is spaced from the projection 22 and adaptedto pass through theaperture 14 1in the handleKY member 6.V

The preise-tiens V.20 and 22 are preferablyl The blade A pressed from,the body of the clampin ele-- ment 18, and the project-ion 2O has an aLrupt shoulder 26 extending approximately at right angles to theclamping element 18`-and a sloping shoulder 28which extends from theouter end of said shoulder V26 backto the body of the clamping element18. The hook 24 has an end portion 30 approximately parallel to thehandle member 16, for a purpose which will hereinafter appear.

In the practical operation of thedevice the spring plate 4 is held withthe projections 20 and 22 and the hook 24uppermost. A safety razorbladeA is then placed upon the blade clamping element 18 in suchposition'that the projections 2O Vand22 will pass .j .l

throufh the slots B and C near the opposite ends lof said blade A.'V Theplate 2 isvthen placed upon the plate 4 and the razor blade A,.with theaperture 14 disposed above the hook 24, after which the plates 2 and 4are pressed toward each other and the plate v'2 then pushed backwardly,orto Yth'eright in drawing, to carry the edge 34 off the aperture 14beneath the end portion 30" of the hook 24, which latterfthen holds the`plates 2 and 4 together. Vhen the plate is pushed'back'wardly' asstated, the hole 1Q is carried` into coincidence with the projection 2 0over which it vsnaps. so that the two clamping elements 8 opposite sidesofthe blade A and coact and 1'8may grip thev sov with the projections 20and 22 in firmlyv holdingsaid blade in. position.` As theV clampingelement 8 snaps into position as described, the edge 35 of the hole 10is carried down into engagement with the abrupt shoulder 26, whichlatter coacts with the hook 24A in preventing accidentallongitudinalmovement of the spring plate 2 in either direction upon theplate 4 and thus becomf ing disengaged from the latter.

As'shown by Fig. 2, the rear end of the spring plate 2 slightly projectsover the corresponding end of the spring plate 4.

Hence, when it is desired to remove Vthe blade A it is only necessary totap said projecting endagainst a table or other objecty i for thepurpose of forcing the plate 2 lon'- gitudinally of the plate 4'untilthe edge 34. of the aperture 14 passes from beneath the overlappingportion 30 of the hook 24. The longitudinal rmovement of the springplate 2 is facilitated by the sloping shoulderQvS,

which enables the rear margin of the' hole 1t) to readily slip over theproject-in 202 The slot 12 is of such length as to permit the plate' 2to move longitudinally of the plate l during the-act of engaging ordisengaging said plates. The foregoing operak tions may be quicklyaccomplished and without danger of cutting the fingers on the sharpedges of the blade A.

From the foregoing description it is apparent that I have provided ablade holding device embodying the advantages above pointed out, andwhile I have shown and described the preferred construction, combinationand arrangement of parts I reserve the right to all suclichanges andn'iodilications as properly fall within the spirit and scope of theinvention as claimed.

Having thus described my invention, what I claim and desire to secure byLetters Patent, is:

l. A device of the character described consisting of two spring platesslightly bowed in opposite directions, lateralv projections on one ofsaid plates adapted to enter openings in the companion plate and'projectthrough openings in a blade placed between said plates, anda hookprojecting laterally from one of said plates and adapted to pass throughan aperture in the other plate, said hook having a sloping surface fordrawing the plates together and against the opposite sides of the bladeand a surface paralleling the associate plate for coacting with one ofthe lateral projections in holding the plates together.

2. A device of the character described consisting of two plates slightlybowed in oppo'siteV directions, lateral projections on one of saidplates adapted to enter a hole and a slot in the companion plate andproject through openings in a blade placed between said plates, and ahook projecting laterally from one of said plates and adapted to passthrough an aperture in the otherv plate, said hook having a slopingsurface for drawing the plates together and against thevopposite sidesof the blade and a surface paralleling the associate plate for coactingwith one of the lateral projections in holding the plates together. oneof which latter is slightly longer than the other.

3. A device of the characteil described consisting of two plates,lateral projections on one of said plates adapted to enter a hole and aslot in the companion plate and' project through openings in a bladeplaced loe-` tween said plates, one of said projections having an abruptshoulder for engaging the margin of the `hole in the companion plate anda shoulder sloping backwardly to the plate from said abrupt shoulder,and a hook projecting laterally from oneof the plates and adapted topass through an aperture in the other plate, said hookhaving a slopingsurface approximately' like said slopingV shoulder and a surfaceparalleling the associate plate for engagement therewith.

et. A 'device of the" character described consisting of two springplates slightly bowed in opposite directions and provided with coactinghandle members and coacting blade-clamping elements, which latter arenarrower Vthan the former, lateral projections on one of said platesadapted to enter openingspin the companion plate and project throughopenings in a bladeplaced between said plates,`and a hook projectinglaterally from one of said plates and adapted to'pass through anaperture inthe other plate, said hook having la surface for enga-'gingthe apertured plate to hold the latter against the companion plate.

In testimony whereof I affix my signature.
